用srping mvc和jpa写一个helloworld,没想到还跑不起来
不知道哪里出错了,可能是配置没做好,这里还请大家帮忙看看是什么没问题。
下面是我的代码:
这是个controller
package com.ll.together.controller;
import com.ll.together.service.LoginBQqService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class HelloWorldController {
@Autowired
public LoginBQqService loginBq;
@RequestMapping("/hello.htm")
@ResponseBody
public String hello() {
loginBq.findAll();
return "mysldks";
}
}
下面是 LoginBQqService
package com.ll.together.service;
import com.ll.together.entity.QqUser;
import org.springframework.data.repository.CrudRepository;
/**
* Created by xiaolongren on 15/6/13.
*/
public interface LoginBQqService extends CrudRepository<QqUser,String> {
}
下面是applicationcontext.xml
<?xml version="1.0" encoding="UTF-8"?>
